I transplanted a whole a/c set up from a v8 hz Stato to my hj pano. Not hard just a bit time consuming and fiddly. I had everything bar the Sandan compressor from the HZ so i used a mates compressor from a VL Commodore. Easy fit after i made the bracket out of 8mm plate. I used that compressor because it was offered to me for free. Its fun.!!!?
